Residential Wiring Practice Exam 2025 – Comprehensive Prep Guide

According to the National Electrical Code (NEC), there is no specified maximum number of receptacle outlets that can be connected to a 120-volt residential lighting circuit, which is why the answer is considered unlimited. This flexibility allows homeowners and electricians to design circuits that accommodate the specific needs of the space without being restricted by a numerical limit on receptacle outlets.

However, it's important to note that while there is no upper limit, other factors come into play, such as the capacity of the circuit and the potential load. A typical 120-volt residential lighting circuit is usually rated for 15 or 20 amps, and the total load should not exceed that rating to avoid tripping breakers or causing safety hazards. Hence, while the code does not limit the number of receptacles, it is crucial to calculate the expected load to ensure compliance with safety standards.

This understanding highlights the importance of considering both the practical application of electrical loads in a home and adherence to the NEC to ensure both functionality and safety in electrical installations.
